Temporal bone cholesteatoma. 1985

R Charachon

Clinical features of temporal bone cholesteatoma are miscellaneous, and sometimes misleading: signs of middle ear cholesteatoma, progressive or sudden facial palsy, sensorineural deafness as in acoustic neuroma, conductive deafness as in otosclerosis, secretory otitis media, or intracranial complications. Polytomography is the only way to pinpoint topography and extension. CT scanning is very useful in determining extension. Topography and severity of deafness are the guidelines for surgical approach. Among sixteen cases, total deafness was produced by the lesion itself in ten cases, and six had an intact inner ear; preservation of hearing was possible in only three. Supralabyrinthine cholesteatomas (five cases) are best managed by the middle fossa approach. Infralabyrinthine cholesteatomas (six cases) must be removed via the infratemporal approach with anterior displacement of the tympanic and mastoid segments of the facial nerve and permanent obliteration of the middle ear. Posterior perilabyrinthine cholesteatoma (five cases) may be removed by the otologic approach combined with the middle ear fossa approach if the inner ear is to be preserved. If hearing loss is total, the translabyrinthine approach can be used.

D008581	Meningitis	Inflammation of the coverings of the brain and/or spinal cord, which consist of the PIA MATER; ARACHNOID; and DURA MATER. Infections (viral, bacterial, and fungal) are the most common causes of this condition, but subarachnoid hemorrhage (HEMORRHAGES, SUBARACHNOID), chemical irritation (chemical MENINGITIS), granulomatous conditions, neoplastic conditions (CARCINOMATOUS MENINGITIS), and other inflammatory conditions may produce this syndrome.

D001922	Brain Abscess	A circumscribed collection of purulent exudate in the brain, due to bacterial and other infections. The majority are caused by spread of infected material from a focus of suppuration elsewhere in the body, notably the PARANASAL SINUSES, middle ear (see EAR, MIDDLE); HEART (see also ENDOCARDITIS, BACTERIAL), and LUNG. Penetrating CRANIOCEREBRAL TRAUMA and NEUROSURGICAL PROCEDURES may also be associated with this condition. Clinical manifestations include HEADACHE; SEIZURES; focal neurologic deficits; and alterations of consciousness.

D002781	Cholesteatoma	A non-neoplastic mass of keratin-producing squamous EPITHELIUM, frequently occurring in the MENINGES; bones of the skull, and most commonly in the MIDDLE EAR and MASTOID region. Cholesteatoma can be congenital or acquired. Cholesteatoma is not a tumor nor is it associated with high CHOLESTEROL.	Cholesteatomas

D005158	Facial Paralysis	Severe or complete loss of facial muscle motor function. This condition may result from central or peripheral lesions. Damage to CNS motor pathways from the cerebral cortex to the facial nuclei in the pons leads to facial weakness that generally spares the forehead muscles. FACIAL NERVE DISEASES generally results in generalized hemifacial weakness. NEUROMUSCULAR JUNCTION DISEASES and MUSCULAR DISEASES may also cause facial paralysis or paresis.
